본 논문에서는 미래의 네트워크 모델에 적합하도록 설계한 생태계 모방 임베디드 미들웨어(BIEM : Bio Inspired Embedded Middleware)를 구현하고, 그의 구조와 특성을 기술하며, 성능을 평가하여 BIEM의 정확성을 검증한다. BIEM의 정확성을 검증하기 위해, BIEM 위에서 응용프로그램을 실행시켰을 때와 독립적으로 일반적인 해를 구했을 때의 결과를 비교한다. 또한 서비스 제공을 위해 요구되는 통신오버헤드를 측정하여, 오버헤드가 네트워크 트래픽에 얼마나 영향을 미칠지에 대해서 알아보고, 마지막으로는 이주서비스에 소요되는 시간을 비교 및 분석한다. 이를 통해, BIEM이 미래 네트워크에 이용될 수 있는 하나의 시스템임을 결론지을 수 있다.

The purpose of this study is to explore the factors affecting the welfare needs of the rural marriage migrant females. A survey was conducted on 300 rural marriage migration females using probability sampling and for the analysis stepwise regression was used. The major findings of this study can be summarized as follows. The welfare needs of counselling on husband' behavior problem were higher in cases of worse mental health, better physical health, younger age and lower participation in the meetings with her fellow countrymen. The welfare needs on the children raising and education were relatively higher among the migrant females from Vietnam and younger age. The needs on the job skills training were lower in cases of the migrant females from Philippines, China(the Chinese) and were higher in cases of lower level of family understanding. The welfare needs on the job placement were higher among older and lower community affinity, and were lower in cases of the migrant females from Philippines. The results suggest that the welfare services should be differently provided to the migrant females in reflection of the age, education level, nationality and community resources. Further, the mental health screening test and treatment services for migrant females are needed since the welfare needs increase when the migration females have worse mental health condition.

The research aims to develop the courses for librarians' continuing education to build up multicultural competencies in library services. In order to achieve the purpose, the study designed the research processes as followings: first, multicultural environment analyses with various materials such as statistics or national reports; second, librarians' and multicultural users' needs analyses of multicultural library services and library works; third, job competency analyses through reviewing related laws, rules, guidelines for library multicultural services, etc. On the basis of the results from the three-step analysis phases, the study deducted the candidate courses for librarians' multicultural education. After testing validity of the candidate courses by expert panels on library multicultural services, the research suggested the final 16 courses and follow-up research projects for designing and implementing the suggested courses in real class fields.

Wireless LAM has the advantage of extension, flexibility and easiness of installation and maintenance. However, due to the characteristics of wireless media, it is vulnerable to security attacks. PKI(Public Key Infrastructure) is estimated to be a good solution offering security function to wireless LAM including global roaming. It offers high security functions as authentication confidentiality and digital signature while it generates big overheads such as CRL search and certificate verification. The overheads can not be avoided during the initial authentication. However, when we consider the case of handoff, it can be minimized through the fast handoff. In this paper, we design a fast handoff authentication mechanism based on PKI in the wireless LAM and analyze the performance of the scheme.

ChatGPT, a generative artificial intelligence(AI) technology that analyzes conversations to identify users' intentions and generates responses in consideration of the context of the conversation, is attracting attention from a user interface (UI) perspective that it can provide information through natural conversations with users. This study examined the effect of functional and playful values experienced by early users of ChatGPT on reuse intention and verified the structural relationship between technological efficacy, experiential values, and reuse intention. To verify the research model and hypotheses, a survey was conducted on college students who used ChatGPT for the first time. A total of 156 responses were received and 154 responses were used for analysis. As a result, both the functional experiential value and playful experiential value in the initial use process had significant effects on the intention to use ChatGPT. In addition, it was found that technological efficiency had a significant effect on functional and playful experiential values.

많은 사람이 "다음 생에 성적 소수자나 이주민, 장애인으로 태어나고 싶니?"라는 질문을 받는다면 대부분 사람은 선뜻 "그렇다"라고 대답하기 어렵다. 그 근본적인 이유는 질문 속 사회적 약자들은 사회에서 다양한 불평등을 마주하고 있다는 의미일 것이다. 본 논문에서는 여러 소수자 중 시각장애인을 위한 보행 보조 기구를 제작하였다. 시각장애인들이 사용하는 지팡이는 지면의 장애물 파악에 도움은 되지만 공중에 떠 있는 장애물을 파악하고 피하기 어렵다. 이러한 단점을 보완하고자 라이다 센서를 이용하여 장애물 감지가 가능한 서비스를 시각장애인에게 제공한다. 라이다 센서는 레이저 광원을 방출하여 목표물에서 튕겨 되돌아오는 특성을 이용하여 사용자에게 전방에 장애물이 감지되면 시각장애인에게 TTS로 경고음을 제공한다.
